[elbe-devel] [PATCH 4/5] elbepack: daemon: properly maintain subapplications PATH_INFO

[Thomas Weißschuh]

The subapplications mounted via the WsgiDispatcher need their PATH_INFO
and SCRIPT_NAME maintained properly.
Use the utility function shift_path_info() from the stdlib to do so.
This also enables some more cleanups.
